1GI pipe in domestic plumbing most commonly means pipe made of:
A.Green insulated PVC only
B.Glass-insulated copper only
C.Graphite-impregnated lead only
D.Galvanised iron (steel with zinc coating)
Explanation: GI stands for galvanised iron: mild-steel pipe coated with zinc to slow rust. It is widely used for cold-water and some outdoor service lines where mechanical strength is needed.
2Which plastic pipe material is generally preferred for hot-water distribution inside buildings because of better high-temperature resistance than ordinary PVC?
A.Rubber garden tube only
B.Unplasticised PVC soil pipe only
C.CPVC
D.LDPE garden hose only
Explanation: CPVC (chlorinated polyvinyl chloride) is formulated for higher service temperatures and is commonly used for domestic hot-water lines, whereas ordinary PVC is better suited to cold water and drainage uses.
3A key advantage of copper pipe for potable water is that it:
A.Is always cheaper than every plastic option in India
B.Is magnetic and used only for gas, never water
C.Cannot be soldered under any condition
D.Resists corrosion well and has long service life when correctly installed
Explanation: Copper is durable, relatively corrosion-resistant in many waters, and accepted for potable systems when jointed correctly. Cost and local water chemistry still need site judgment.
4PVC solvent-cement joints rely mainly on:
A.Molten lead poured into the socket
B.Magnetic attraction between pipe and fitting
C.Softening and fusing the plastic surfaces so they weld together
D.Only friction from a dry push-fit with no cement
Explanation: Solvent cement softens the PVC/CPVC surfaces so they fuse as the solvent evaporates, forming a solvent-welded joint when size, cleanliness, and cure time are correct.
5Compared with PVC cold-water pipe, CPVC is chlorinated primarily to:
A.Make the pipe electrically conductive
B.Convert it into a metal alloy
C.Eliminate the need for any supports on long runs
D.Improve resistance to higher temperatures for hot-water service
Explanation: Chlorination of PVC produces CPVC with higher heat resistance, making it suitable for domestic hot-water lines within manufacturer temperature limits.
6Which statement about GI pipe threads is most accurate for site work?
A.GI pipe is never threaded; it is only solvent cemented
B.GI pipe can only be joined by soldering with soft tin-lead solder
C.Threads must always be left completely dry with no sealant
D.Threads are usually cut with a die set and sealed with suitable thread sealant or tape
Explanation: GI pipe is commonly threaded with pipe dies. A proper thread sealant or PTFE tape (applied correctly) helps seal the metal-to-metal joint against leaks.
7Why is ordinary PVC generally avoided for continuous high-temperature hot-water lines?
A.It is illegal to use PVC for any cold water anywhere
B.It is an excellent conductor of heat only
C.It softens and loses strength at temperatures where CPVC remains serviceable
D.PVC always expands less than steel, so it never needs supports
Explanation: PVC softens as temperature rises. Hot-water service is typically assigned to CPVC, copper, or other materials rated for the design temperature.
8Zinc coating on GI pipe mainly protects the steel by:
A.Making the pipe as flexible as rubber hose
B.Eliminating the need for any earth continuity on bonded systems
C.Sacrificial/barrier protection that slows rusting of the base metal
D.Converting steel into stainless steel
Explanation: Galvanising coats steel with zinc, which acts as a barrier and provides sacrificial protection, extending service life in many water and outdoor exposures.
9When selecting pipe for an outdoor cold-water main that may face mechanical impact, which material is often chosen for toughness over pure plastics?
A.GI (galvanised steel) pipe
B.Unreinforced paper duct only
C.Thin glass tubing only
D.Open foam insulation alone used as the pipe
Explanation: GI provides higher mechanical strength and impact resistance than thin plastics for many outdoor or exposed runs, though corrosion and joint quality must still be managed.
10Copper tube used with capillary solder fittings must be:
A.Always painted with bitumen before soldering
B.Joined only when the tube is full of pressurised water
C.Clean, oxide-free, and properly fluxed before heating
D.Covered in thick oil so solder cannot wet the surface
Explanation: Successful copper capillary joints need clean metal, correct flux, and controlled heat so solder draws into the joint by capillary action.
